Answer:
naturalistic observation.
Explanation:
Cal believes that a larger percentage of a city’s population will engage in public displays of affection in highly populated cities due to feelings of anonymity when an individual is among a lot of other people. He rides a bus in densely populated New York City for five hours straight, watches the bus riders’ interactions with each other, and unobtrusively counts the number of couples who are holding hands, hugging, or kissing. He then does the same in the sparsely populated city of Rock Falls, Iowa. The research method Cal used is known as naturalistic observation.
As we know that Naturalistic observation is a research method which is used commonly by psychologists and other social scientists. in this technique, it involves observing subjects in their natural environment.
Answer: B) So they can communicate their results without confusion
Explanation: There are other systems besides the metric system, though the metric is the most commonly used system. In the SI international system, all units are derived from each other, forming a unique international standard. That way, all scientists around the world, or at least most of them using the SI system, can communicate in a unique scientific "language" without confusion and misunderstanding.
This "Necessary and Proper Clause" (sometimes also called the "Elastic Clause") grants Congress a set of so-called implied powers—that is, powers not explicitly named in the Constitution but assumed to exist due to their being necessary to implement the expressed powers that are named in Article I. The Bank's existence is a great example of implied powers: the Constitution doesn't say that Congress has the right to establish a bank, but its defenders claimed that one was necessary to carry out the Congress' power to collect taxes. Hope this helps.

Answer:
Listeners can become lost
Explanation:
Informative speakers need to judge their audience before they speak. They need to know some facts about their listeners, where do they come from, from which background socially and ethnically, and they may want to know something about their religion or interests. This way they can judge the level of the audience's knowledge about the subject they will speak upon.
If the informative speakers overestimate the listeners' knowledge on a particular subjects, the listeners will become frustrated because they won't understand what the speakers are telling them. They may consider themselves to stupid or not knowledgeable enough to listen to this speech. After trying to understand, they give up in the end and <em>can become lost</em>, not understanding the speaker and the topic he speaks upon.
